CALENDAR.

SPECIFICATION forming part of Letters PatentI No. 328.768, dated October 20, 1885.

Serial No. 157,869. (No model.)

To all whom, it may concern,.-

Be it known that I, WALLACE T. FENN, of NVethersiield, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Perpetual Calendars, of which the following is a description, reference being had to the accompanying drawings, where- Figure l is a plan view of my improved calendar. Fig. 2 is a sectional View of the same. Fig. 3 is a detail view of the monthdisk of the calendar.

My improvement relates to the class of calendars called perpetuah and it consists in the peculiar combination or disks bearing numbers and names, respectively, and so arranged that by the rotation of one or more of the disks the calendar may be set for the current month, as more particularly hereinafter described.

In the accompanying drawings, the letter a denotes the base-card, that may be of any desirable size, and bears in a circle, b, the figures from l to 3l, but so arranged that the figures 29, 30, and 3l overlap the figures l, 2, and 3, thus making the circle, as a whole, divisible by seven. Next over the base card is attached a circular disk, c, with the days of the week arranged four times in succession, and radially, upon the outer edge of the disk, which is of proper size to bring the names ofthe days of the week close to the dates. Next in order is the circular disk el, which bears the names of the months, arranged radially part of the Way around the face of the card, near its edge, and opposite to each of these names ofthe month and in the same line is the number denoting the number of days in the several months, respectively.

The last disk, e, may be called the coverdisk,77 and this bears diametrically opposite each other the slots e e, through which appears on one side of the center the name of a month and on the other the number of days in that month. This cover may be plain or bear any desirable print, figure, or card of printed matter.

The several disks are preferably connected by means of a common pivot, f, that fastens them together through the center, and the calendar is set for any given date by turning each disk on this pivot as a center.

The main improvement resides in the com bination of the gures, arranged to overlap in the outer circle, With the seven days of the Week four times repeated on the next rotary disk; but a further improvement consists in the combination, with these, of the peculiar month-disk and the slotted cover-disk.

It will be noticed that the names of the months are arranged to read from one side half-way around, and are reversed on the other half of the disk; and to prevent the turning of the disk so far around as to present these names upside down, the edge of the disk, near its upper side and for a limited distance each side of the center, bears a number of dots or marks which register with the index-mark on the base-card and limit the play of the Week-disk.

I claim as my invention- 1. As a new article of manufacture, a perpetual calendar consisting of a base-card bearing the series of numbers from 1 to 31, arranged in a circle, with the last three overlapping the first three, in combination with superimposed rotary disks bearing the names of the days of the Week and months, respectively, and pivoted to the base-card, all substantially as described.

2. In combination, in aperpetual calendar,

a basecard, a, having the series of iigures b, arranged in a circle with the ends overlapping, the disk c, having the names of the days of the week radially arranged near its edge, the disk d, bearing the names of the months and the number of days in each, arranged diametrically opposite each other on the disk, the cover-disk e, with slots e c, and the pivot f, all substantially as described.

3. In a perpetual calendar, the numbers from 1 to 8l, arranged about a center, with the last three numbers overlapping the first three, in combination with the names of t-he days of the week four times repeated, the numbers and names being borne on separate cards or slips moving on each other, all substantially as described.
